18    Description:
19    
20      This update synchronizes my repository with Yale's.  Most of these
21    changes, however, do not affect SML/NJ at all (the RA is an exception).
22    
23    1. Register Allocator
24    
25       a. An improvement in the interference graph construction:
26          Given a copy
27    
28                s <- t
29    
30          no interference edge between s and t are added for this definition of s.
31    
32       b. I've added two new spill heuristic modules that Fermin and I developed
33          (in the new library RA.cm). These are unused in SML/NJ but maybe
34          useful for others (Moby?)
35    
36    2. X86
37    
38       a. Various fixes in the backend provided by Fermin [C--] and Lal.
39    
40    3. Alpha
41    
42       a. Added the BSR instruction and code generation that goes with it [C--]
43       b. Other fixes too numerous to recount provided by Fermin [C--]
44    
45    4. Regmaps
46    
47       a. The regmaps are not initialized with the identity physical bindings
48          at creation time.  This is unneeded.
49    
50    5. MLRISC Optimizations
51    
52       a. The DJ-Graph module can now compute the iterated dominance frontiers
53          intersects with liveness incrementally in linear time! Woohoo!
54          This is now used in my new SSA construction algorithm.
55    
56       b. THe branch reorganization module is now smarter about linear chains of
57          basic blocks.

64    Description:
65    
66    Changed install.sh script to handle archive files without version number
67    and to use "boot.<arch>-<os>" instead of "sml.boot.<arch>-<os>" for the
68    name of the boot file archive.

87    
88    1.  Yet another fix for x86 assembly for idivl, imull, mull and friends.
89    
90    2.  Miscellaneous improvements to MLRISC (unused in sml/nj)

96    Description:
97    
98    Improved handling of branches (mostly those generated from
99    polymorphic equality), removed switchoff and changed the
100    default optimization settings (more cpsopt and less flintopt).
